... and 426.85 °C). Optimum mixtures of hydrocarbons and carbon dioxide have been worked out for use as working fluids in the above temperature range. This study shows that the use of multicomponent mixtures results in higher efficiency and smaller systems suitable for solar-powered small-scale power cycles...

...H. Baca; D. E. Nikitopoulos; J. R. Smith; A. T. Bourgoyne Results from experiments conducted in downward liquid-gas flows in inclined, eccentric annular pipes, with water-air and water-polymer-air mixtures as the working fluids, are presented. The gas was injected near the middle of the test...

... and dependent on the flow velocities of the two-phase fluids. Wax deposition occurs only along the pipe wall in contact with a waxy crude oil. An increase in mixture velocity results in harder deposits, but with a lower deposit thickness. The wax buildup trend at low mixture velocities is similar...

...Partha S. Bishnu; Djamel Hamiroune; Mohamad Metghalchi Two constrained equilibrium codes, GNASA and GSTANJAN, have been developed which determine the composition of constrained equilibrium gas mixture. These codes use NASA and STANJAN equilibrium programs as the basis for generalized equilibrium...

...Yuri V. Fairuzov, Assoc. Mem. ASME; Pedro Arenas-Medina; Jorge Verdejo-Fierro; Ruben Gonzalez-Islas Full-scale experiments were conducted in order to investigate flow pattern transitions in horizontal pipelines carrying oil-water mixtures. In the experiments, a 16-in. pipeline conveying light crude...

... is unavailable or insufficient. Saturated forced convective boiling for binary mixtures has been considered to account for the reduction in the heat transfer coefficient observed for most mixtures. The simultaneous solar and gas-fired desorption process was investigated. The generator constructed based...

... downward flow in inclined and vertical pipes may lose pressure at high mixture velocities and gain pressure at low mixture velocities. 2 Pipe inclination angle, inside diameter and roughness and fluid physical properties have significant effects on the pressure loss/gain boundary of gas-liquid downward...

...Mamdouh M. Salama, Fellow ASME The current practice for eliminating erosional problems in piping systems is to limit the flow velocity V e to that established by the recommended practice API RP 14E based on an empirical constant ( C -factor) and the fluid mixture density ρ m as follows: V e = C / ρ...
